ABSTRACT
The study was conducted to evaluate the economics and effectiveness of Trichogramma and earwigs in the suppression of corn borer and identify other corn pest associated during vegetative stage using light trapping. A Randomized Complete Block Design was used in laying out the experiments with five treatments as follows Treatment 1-Control, Treatment 2-Trichogramma, Treatment 3-Earwigs, Treatment 4-Light Trapping and Treatment 5-Trichogramma + earwigs. Based on the analysis of variance it revealed highly significant variations among treatments with regards to number of parasitized and unparasitized egg mass of corn borer at 35 and 45 days after planting. In like manner, the damage assessment done by corn borer differed significantly at 35 and 45 days after planting. With regards to weight of green corn grains per sampling area, a highly significant differences was observed among the treatment means. The combination of Trichogramma and Earwigs showed high effectively in the field by exhibiting the highest computed yield per hectare and higher return of investment per peso invested.
